Swimming has a variety of health benefits and is a great way to get your exercise while staying cool. It can reduce stress, boost your metabolism and improve sleep quality. It can also help relieve depression and anxiety. And it’s a fun activity to do with friends and family. So why not make it a part of your summer routine?

While the Hong Kong’s beaches and pools are slowly reopening, some are only partially open due to the shortage of lifeguards. That’s bad news for swimming clubs, who might need to cancel classes and lose members.

Nearly half of Hong Kong’s public pools are likely to close lanes and facilities reserved for swimming lessons this summer due to a staff shortage, a union said on Tuesday. The Hong Kong Recreation and Sports Professionals General Union (HKRSPGU) said 20 public pools had told swimming clubs they would not be able to open fully this summer, without giving any reason.

The HKRSPGU, which represents more than 1,200 recreational and sports professionals including coaches, swim instructors and gym teachers, said a full reopening of public beaches and swimming pools was “unlikely” this year because of a shortage of qualified lifeguards. The government’s Leisure and Cultural Services Department (LCSD) has been trying to address the problem by increasing salaries for seasonal lifeguards and recruiting new recruits on two-year contracts.

Fortunately, the city has plenty of indoor and outdoor public pools that offer both lap swimming and public swim sessions. Most of them require a membership fee, but you can always visit during an open-swim session for free. Some even offer aquatics programs for all ages and abilities.

Here are five of the city’s best pool destinations:
